This plot shows the power spectrum in arbitrary units (P) as a function of frequency (f), for the light curve of a solar type star (see related images). The spectral analysis of the light curve, reveals small periodic components in the expected domain from 1.5 to 2 mHz. These periods, corresponding to modes of oscillation of the star will be studied and interpreted to understand the star's internal structure and determine its age.
